Toasted Marshmallow Sweet Potato Crumble



Toast it a little or toast it a lot, depending on your marshmallow preferences.

Most of my friends can tell you that I have a heart for s'mores. With Thanksgiving around the corner, it's only natural for me to combine a beloved seasonal dish with a year-round favorite. The toasted marshmallow sweet potato crumble was born. So it goes. Though its name reads ultra indulgent—I mean, it is the holidays—the result isn't overly sweet. I cut back on the sugar and butter that most sweet potato casseroles call for and added a nice crumble topping in order to usher in the decadent maple-infused marshmallow creme.

You might be used to, in fact, you probably adore your momma’s sweet potato casserole, but I dare you to try this, even if just for the toasted pillowy, maple marshmallow creme. I adapted my marshmallow creme recipe from Bon Appetit by infusing the creme with maple syrup for the extra autumnal dose that we all love during Thanksgiving. Yes, my marshmallow topping appears pretty darn toasted, but I promise you—and the crowd of people I shared this with can attest—that its toastiness doesn’t sacrifice the flavor one bit. Once the sweet potato filling meets the oat-pecan crumble followed by a mouth of ‘mallow, it’s as if you’re smack dab around a campfire on Thanksgiving Day.

1 tsp vanilla extract

For the sweet potato filling, place chopped potatoes in a pot and cover with water. Bring to a boil, then reduce to a simmer for 20 minutes or until potatoes are tender. Drain potatoes and transfer to a large bowl. Mash potatoes, then add remainder of ingredients for sweet potato filling and mix well. Transfer to a cast-iron skillet.

To prepare oat crumble, mix all ingredients in a bowl. Sprinkle oat crumble over top the sweet potato filling. Bake for 25 minutes.

While baking, prepare marshmallow creme. In a stand mixer, add egg whites to the bowl. With a whip attachment, whip on high speed until frothy. Slowly add sugar, and whip until medium peaks form. Lower to medium speed, and pour in maple syrup. Increase to high speed, and whip until you have dense, stiff peaks.
